Zac and The Rock star as two mismatched lifeguards, Matt Brody and Mitch Buchannon, who put aside their personal differences to stop a criminal mastermind's drug trafficking operation.

We can also expect a special cameo appearance from David Hasselhoff, who spoke about passing the baton on to Dwayne.

"It was kind of a bittersweet thing when you go on the set and someone else is playing Mitch Buchannon," David told E! News. "I said, 'Well I'm Mitch Buchannon,'" he recalled. "We had a big laugh about it."

He said the secret to playing the iconic role of Mitch is to "Be cool, have fun and save lives."

We're not sure what his cameo appearance will involve but The Hoff said the film's producer Beau Flynn "couldn't have been more gracious, he let me do what I wanted to do, and we'll see what happens."

The original series ran from 1989 to 1999 before being renamed Baywatch: Hawaii and running for a further two seasons.
